MethodsMulti-center cross-sectional survey method and systematic sampling method were used to select patients at fifteen hospitals in Chongqing from August to November in 2019. Then reflux symptom index（RSI） was investigated. At the same time, the information of the relevant dietary habits, including smoking and drinking, spicy diet, high-fat diet, and satiety was collected. Moreover, the factors related to LRPD（gender, age, symptoms, diet and lifestyle） were analyzed. ResultsThe composition ratio of LPRD was 11.90%（385/3234） in 3234 effective questionnaires and 385 positive ones. The composition ratio was 12.55%（173/1378） in men and 11.42%（212/1856） in women. The difference between the two groups was statistically significant（P less then 0.05）. The difference in composition ratio among different age groups was statistically significant（P less then 0.05）, with the highest composition ratio between 40 and 59 years old（170/1390）. Constant throat-clearing（symptom 2） and globus sensation（symptom 8） were most correlated with LPRD. Logistic regression analysis showed that spicy diet, over eating, and smoking were highly related to LPRD. ConclusionGlobus sensation and constant throat-clearing are the most common symptoms in LPRD patients. Spicy diet, over eating, and smoking are risk factors for LPRD.ObjectiveTo explore the predictive factors for asymptomatic airway hyperresponsiveness（AAHR） in patients w
